Ah, that sucks. I'm sure you'll do better on the re-sit. How did you do in the coursework?
Hmm, I'm not sure what advice to give, really. I just made sure I knew all the Assessment Objectives inside-out, did as many practice essays as possible, did a lot of wider reading, and made sure I was familiar with The World's Wife. But really I just had a lot of passion for the subject, so I put a lot of work into it.
Make sure that, for Section A, you focus on AO4 -- context: how the time of the extract's publication/conception affects its thoughts and feelings with regards to the 'struggle for identity', and then explain whyreaders at the time would respond differently to readers now. Do the same for wider reading. You also focus on AO2 -- how form, structure and language shape meaning. For example: 'In The Woman Who Walked Into Doors, Doyle uses a non-linear structure [provide evidence], showing the fragmentation of Paula's mind and life.'
For Section B, AO1, AO2 and AO3 are all equally important, and AO4 gives no marks. So you need to focus on terminology and your written style (AO1 -- basically how you write), language structure and form (AO2), and make comparisons to other poems and give alternative interpretations (AO3).
Good luck
